How much heat is required to kill bacteria in food?
It's a combination of time and temperature and depends which bacteria. Generally most bacteria causing food borne illnesses die off above 130F(throughout the meat, so not just the outside) held for enough time. Poultry has salmonella risk which can survive higher temperatures. If you want to kill it faster, it requires higher temperature. This won't kill off all bacteria(things like botulism spores can survive boiling temperatures), but to reduce the dangerous ones to a safe level can be seen in this chart:Source: http://www.cookingissues.com/ind...Temperature is a function of heat and various other factors that would be too complicated to list here.
The biggest cause of foodborne illness is?
when you do not keep the food hot enough, or cold enough, it is unsafe, because the bacteria grows fastest at a medium range of temperatures. geometric growth (bacteria) patterns means that very little time is needed to make bad food. the amount of time that it takes for it to make you sick changes with the actual food-borne illness.
How does bacteria cause food borne illness?
Foodborne illness (also foodborne disease and colloquially referred to as food poisoning ) is any illnessIllness resulting from the consumption of contaminated food. There are two types of food poisoning: food infection and food intoxication. Food infection refers to the presence of bacteria or other microbes which infect the body after consumption. Food intoxication refers to the ingestion of toxins contained within the food, including bacterially produced exotoxins, which can happen even when the microbe that produced the toxin is no longer present or able to cause infection.
Does hot water or cold water kill bacteria?
Hot water will kill a small portion, water simply does not get hot enough to kill most microbes on contact (without a sanitizer or additive of some type). To kill a majority of the common bacteria that cause foodborne illness, superheated steam would be required. Granted this is without sanitizers/cleansers... purely superheated steam at the right temperature and time application.
What three things does bacteria need to grow?
moisture, nutrients, warmth. Not all bacteria need oxygen to reproduce.Anaerobic bacteria produce energy without oxygen.
